MACHINE FOR GLAZING BISCUITS.

To all whom it may concern:

Be it known that we, WALTER RUiuMEL and FELIX SCHMIDT, both subjects ofthe King of Prussia, German Emperor, and residents of the free town ofHamburg, in the German Empire, have inventeda new and useful Machine forGlazing Biscuits, of which the following is an exact specification. I

Our invention relates to a machine by means ofwhich ried on over theroller until they reach the lower side of the latter one, whence theyare scrapedloff bya plate moving in a horizontal direction. Thisscraping off tion has to be thus adjusted to take place immediatelyafter the finish of each turn of the square roller, i. after one side ofthe roller faces the ground and with it an adhering biscuit on theconveyer. As thebiscuits are scraped ofi in turn they drop upon a secondendless band but with the coated side up and are conveyed through aheated chamber in order to be dried, on the other side of which theydrop into suitable boxes or baskets.

In order to make our invention better understood we accompany same witha drawing, where Figure 1 represents a sectional side-view of aconstructional form of the machine, and Fig. 2 a top view of the feedingappliance.

Here a represents a vessel filled with the liquid coating substance, e.9. sugar. Through this sugar-bath the endless conveying band t iscarried, thus being coated with a thick layer on both sides, when comingout of the bath. While ascending the band passes two scraping knives,one on each side. The inner one b is placed in close contact with-theinner surface of the band, in order to make a clean scrape; the outer:knife 0 is set so as to allow a certain thickness of the sugar coat topass on, whereas the surplus is scraped'ofi. By means of thisarrangement the inner surface of the traveling band is freed entirely ofthe sugar coat, whereas on the outer surface a perfectly even coating iscarried on over a roller 'w and under the feeder arrangement the latterconsisting of a reciprocating table d, a fixed cross piece e, goingacross the whole length of the table d and a suitable number of smallpartition plates g. i The positionof the fixed cross piece e can beadjusted across the width of the table by a screw f and a slot h, asshown in Fig. 2.

The partition plates 9 are adjustably fastened to the Specification ofLetters Patent. Application filed January 4,1907. Serial No. 350.309.

Patented July 2, 1907.

cross piece e by means of screws 2', so that the space be-- tween themcan be regulated according to requirements, 1'. e. the width of thebiscuits placed between.

The reciprocating motion of the table is imparted to same by means ofthe lever arrangement I: in suitable connection wit-lithe main drivingpowcr.

The biscuits are placed by hand upon the table d between the partitionplates 9 with the side to bc coated turned toward the table. Now, ifthis table moves backwards, the biscuits hit against the fixed crosspiece 0 and are pushed off the table thereby, dropping upon the coatcdupper surface of the conveyor band t. The

latter one passes over a small intermittent roller lon to a squareshaped roller 1 and thence over another small roller y to the bottomroller 2 in the sugar tank a. The square roller c has agear wheel 0fixed to it that meshes into another gear wheel p. Keyed to the sameshaft of the latter ivhccl is a. ratchet (1 moved by a pawl 'r. Thispawl is driven by an eccentric s by means of suitable connection rods11. and 'n, and a pivoted rocker lover :t. The jerking motion impartedby the pawl 1- to the ratchet q has to be such, that each turn of theeccentric s will cause the square roller 12 to be turned 180, whichresult is achieved by the proper relation of the meshing gear Wheels 0and p. This jerking motion of the square roller '0 is transferred to theconveying band t, the latter carrying along each biscuit placed on samewith a likewise interruptedmotion, until it reaches the upward facingside on the square roller. The next jerk imparted to this roller willcause this upward directed side to face down. In moving it pullp alongthe band portion on top of it, and the biscuit, by means of the adhesivepower of the sugar coat and on account of its own lightness sticks tothe band and is carried along to the under side of the square rolleralso, making thereby a complete turn of 180. As soon as this turn iscompleted, a scrape off plate m arranged at the lower side of the squareshaft 1) is put in a horizonal motion, by means of which the adheringbiscuit is pushed off the band and dropped with the glazed surfaceupward upon-a second endless 'band A, which runs through a chamber B,the latter bechamber for the purpose of being dried and after this Afinal manipulation they are at the other end of the chamber dropped intoa suitable basket or box placed there for the purpose.

The movement'of the scraper m is accomplished by means of a separatelever-construction, indicated on the drawing by connecting rods D and F,and pivoted rocker levers G and H. The latter lever has'two projectingarms, of which the upper one carries a roller I, that travels upon theout-line of the cam K, the latter is firmly attached to the same shaftof eccentric s. To the lowerprojection of lever H a cable L is attached,that runs over a trolley M and carries a weight N at its end for thepurpose of assuring a continued contact between the roller I and the camK.

The afore mentioned square section of the roller '1) forms averyessential part of our invention, for if the 'roller be round, thebiscuits would be pushed back to the upper side of the band if onaccount of the strong adhesive power of the sugar mass, as has beenproved by numerous experiments made. I The prismatic shape of the rollerr firstly hinders a pushing back of the biscuits, secondlyassures areliable and complete turn of the biscuit and, thirdly, renders possiblea scrapiiig off by a horizontal movement and sure dropping of thebiscuit with glazed side up. The square sectioned form has been selectedby us as being the most suitable and practical section, but any othersharp-cornered section, for instance, a triangle, a pentagon, a hexagonor an octagon could be employed without departing from the principalidea of our invention.

Having thus fully described the nature of our said invention, what Wedesire to secure by Letters Patent of the United States is 1. In amachine for the purpose or glazing biscuits and articles of similarcharacter on one side automatically a feeder appliance. consisting of areciprocating table ((1), a tixed cross piece e. adjustably arranged byslot It and screw f as to its position across the width of the table,

a suitable number of partition plates g. adjustably arranged oncrosspiece c for the purpose set forth, and an endless band 1 stretchedover rollers and conducted through a sugar tank 11 and underneath thetable (1, upon which band the biscuits are dropped with the surface tobe coated by the feeder.

2. in a machine for the purpose of glazing biscuits and articles ofsimilar character on one side automatically :1 prismatic shaped roller('0), best of a square section, over which the endless hand (t) isstretched and which is placed at the end of the machine. where thebiscuits are to be taken off the endless band (t).

which the endless band (t) is stretched and means for turning the roller180' at regular intervals oi time, causing thereby a correspondingmoving of the endless band for the purpose set forth.

'4. In a machine for the purpose of glazing biscuits and articles ofsimilar character on one side automatically a feeder appliance incombination with a prismatic roller of a sharp cornered section beingturned suitable degrees according to the form of section selected anendless band t stretched over said prismatic roller 1: and ahorizontally moved scrape off plate (11:) arranged below the prismaticroller (1:) for the purpose of detaching the coated biscuits from theendless band and dropping same on a second conveying band (A) with theircoated surface up.

in a machine for the purpose of glazing biscuits and articles of similarcharacter on one side automatically the combination of a feederappliance with a prismatic roller l; of a sharp cornered section, meansfor turning the roller suitable degrees according to the form of sectionselected at regular intervals of time, an endless hand i stretched oversaid roller a scrapeotf plate in and the means of moving the latter .ina horizontal direction consisting ot cam K roller I, in connection withrod F and l) and rocker G and II. I

6. In a machine for the purpose oi glazing biscuits and articles ofsimilar character on one side automatically the combination of a feederappliance 11. c. y with a prismatic roller 1' of a sharp corneredsection. means for turning the roller suitable degrees according to theform of section selected at regular intervals of time, an endless band tstretched over said roller 4". a scrape-elf plate in means for movingsame horizontally and two scrape-oft knives c and b one attached to theinner and one to the outer surface of the traveling band i for thepurpose as described and set forth.

In witness whereof we have hereunto set our hand in the presence of twowitnesses.
